HVAC Oil Charge Pump with Backflow Prevention, Manual Refrigeration Oil Injector, 200 PSI, 2.6 oz per Stroke, 1/4" SAE for AC Compressor Service

The ROGVOC HVAC Oil Charge Pump is designed for efficient oil injection in modern air conditioning and refrigeration systems. Suitable for use with compressors in residential and light commercial applications, it supports routine maintenance, oil charging, and system servicing. With a working pressure capacity of up to 200 PSI (14.5 bar), this manual pump allows oil to be introduced into the system without the need for full shutdown or depressurization. This helps streamline service procedures and improve efficiency when working in time-sensitive environments. The pump delivers up to 2.6 oz (78 mL) per stroke, providing consistent oil transfer for HVAC systems. This efficient output helps reduce the number of pumping cycles required during oil charging operations. A built-in backflow prevention design helps minimize reverse oil movement during operation, supporting more controlled injection and stable system performance. Equipped with a standard 1/4" SAE connection, the tool is compatible with common HVAC service ports. It works with a range of refrigeration oil types and container sizes, including 1, 2.5, and 5 gallon tanks. A 35 in (90 cm) charging hose is included for immediate use in the field. Constructed with metal components and a sealed internal structure, the pump is designed for repeated service use. For best performance, it is recommended to store the unit in an upright position after operation.
